There are 3 examples of processing of encapsulation formats:Encapsulated Format Converter: The simplest ffmpeg-based package Format converter (no codec)AV Splitter Simplified version (demuxer-simple): Simplest ffmpeg-based package format processing: AV splitter simplified version (demuxer-simple)AV Splitter (demuxer): The simplest ffmpeg-based package format processing: AV Splitter (demuxer)AV

This is a creation in Article, where the information may have evolved or changed. I began to become a Gopher 10 months ago, without turning back. Like many other gopher, I quickly discovered that simple language features are very useful for quickly building fast, scalable software. When I first started learning Go, I was playing with a different multiplexer (multiplexer) that could be used as an API server

The use of basic IO and the simplest example of blocking the server are described in the previous article, and this article introduces the relevant content of the following NIO, which you can refer to in the previous share: Basic knowledge and concepts of network IO General IO and Bio server Use of NiO with server Hello World Netty Getting Started with server Hello World Netty in Layman's NIO, also known as New-io or Non-blocking-io, is understood as non-block

the request model .This model lacks elastic scalability, the number of processing threads on the server and the number of concurrent accesses to the client are 1:1, and the number of threads is inflated resulting in a significant decrease in efficiency, even when the thread's stack overflows and the new thread cannot be created.Pseudo-Asynchronous IO communicationUse the thread pool to be responsible for connections.encapsulates a user's request into a task and then throws it into the thread po

external third-party sensor is used only when the external sensor is connected (and has limited performance). The I2C interface used to send motion data is optional, because the SPI interface is reused, so only two is selected.MPU9250 I2C Interface:I2C interface for third-party sensors This interface is used to connect to the external Third-party sensor, that is, if you feel that the MPU9250 9-axis sensor is not enough, you can also external third-party sensors, such as pressure sensors.This ad

to install, Walkair systems can transmit carrier based carriers, providing class TDM (Time division Multiplexing) services and efficient IP connectivity.As a combination of this best solution, Alvari base allows operators to have unprecedented flexibility in selecting customer addresses and providing services. Alvari base enables operators to quickly and efficiently create broadband wireless access systems and provide solutions that have the benefits of Walkair and breeze access on a single inf

Before establishing a dormitory network, you need to know the networking types. Generally, the LAN topology can be divided into BUS-type BUS, star, ring, and other types. Set up dormitory Network: Nic Network adapters can be divided into AUI, BNC, and RJ45 connectors by connection type, they are used to connect three different network cables, namely, AUI cable, RG-58A/U wire pair [including unshielded UTP) and stranded twisted pair STP). Due to cabl

transmitted to the user in the form of optical fiber, then, the optical terminal is converted into a pair of coaxial (BNC). If the wide-area port of the user's router is in the serial port format (for example, V.35), in order to convert the BNC to the serial port, the Protocol converter is required. That is to say, the input of the Protocol converter is a coaxial cable, while the output is a serial port. T

determines whether to forward the packet by judging whether the destination address and source address are in the same network segment, generally, a small office network device has only two interfaces, one connecting to the Internet and the other connecting to a LAN Hub or switch. Therefore, it is generally set to a default route, as long as it is not an intranet segment, all Forwarding is performed ｡ In the Wan project, the Protocol converter is a telecommunications terminal device used at bot

interface Common Ethernet interfaces include AuI, BNC and RJ-45 interfaces, as well as FDDI, ATM, Gigabit Ethernet and so on all have corresponding network interfaces, the following describes the main LAN interfaces. (1). AuI PortThe AuI port is the interface used to connect to the coarse coaxial cable. It is a "d" Type 15-pin interface, this is one of the most common ports in the ring or bus network. The router can connect to the 10base-5 network th

, to indicate the warranty and replacement time of various accessories and other after-sales services, then let the merchants assemble their computers. After some simple machine check, you can pull the computers back and start networking. Section 3 network hardware selection Of course, the choice of network hardware is inevitable when you set up a LAN in an Internet cafe. Generally, the main hardware devices required to set up a star LAN are network transmission media such as NICs, network cabl

Vro NetworkThe location is complex. It can be an internal subnet edge or an internal or external network edge. At the same time, to achieve strong applicability, it needs to connect to a variety of networks, so that its interfaces must also be diverse. Not to mention network enthusiasts, but many network administrators cannot make it clear. To this end, I would like to introduce all kinds of interfaces and Connection Methods of routers.　　I. router interfaceA vro has powerful network connection a

A LAN interface Cable Standard 1, 10base-t: twisted-pair cable, the general use of RJ-45 connectors, the maximum effective transmission distance is from the hub 100m, even the high-quality 5-type twisted pair can only reach 150m. Its matching resistance is 120 euro. 2, 10BASE5: Coarse coaxial cable, the use of plug-in joints, baseband signal, the maximum support length of 500m, the maximum number of segments is 100. Its matching resistance is 75 euro. 3, 10Base2: Fine coaxial cable, the co

Engineering design will have a decisive impact on the whole wiring process, therefore, the designer should carefully and carefully, do a full investigation, collect relevant information (including some of the building drawings, decoration drawings and other works of information, as well as wiring information, etc.), and should take full account of economic conditions, application needs, The construction progress request and so on each aspect. Engineering wiring should pay attention to the follo
